ORNAMENTAL CHAIN-HOOK.

SPECIFICATION forming part of Letters Patent No. 307,833, dated November 11, 1884.

Application filed July 30, 1894. (No model.)

To all whom itmay concern:

Be it known that I, CHARLES F. BEYERLE, of Providence, in the State of Rhode Island, have invented an Improvement in Safety Hooks for Ornamental Chains, of which the following is a specification.

Figure l is a side elevation of my improved safety-hook when closed. Fig. 2 is a side elevation of the same when open. Figs. 3 and 4. are longitudinal sections of the shank, showing the pushrod in elevation. Figs. 5 and 6 are elevations of the hook-arm separate from the shank. Fig. 7 is a detached elevation of the push-rod and its operating-spring. Fig. 8 is an inside elevation of the shank with the hook-arm removed.

In the accompanying drawings, A is the chain, which is secured to the hollow shank B of the hook by means of the fixed eye '0. At near the outer end of the shank B is pivoted the hook-arm D, the outer end of which is provided with the hook-stud a, adapted to pass within the orifice 12, made in the side of the hollow shank. Within the cavity of the hollow shank B is placed the locking-catch push-rod E, extending lengthwise of the shank B, and terminating in an accessible ball or push knob, c. The push-rod E is preferably formed of a round piece of wire, which is flattened at the points 6 and f, and provided with a perforation, 9, adapted to engage with the hook-stud c, in order to lock the hook-arm D, and also with a slot, h, adapted with afixed pin, 73, which passes through the sides of the shank B, to form a limiting-stop for the upward movement of the push-rod and catch E, the lower end of which is provided with an enlargement, j, below which, within the hollow of the shank, is placed the spiral spring k, which serves to press the rod E upward against the limiting-pin i. The hook-arm D is provided with a downward extension, m, adapted to support and strengthen the hook when closed, and to provide a convenient finger-piece for opening and closing the hook. \Vhen the hook is closed, as shown in Fig. 1, the hook-stud a will be securely locked in the perforation g of the rod E, the end of the stud.

a being rounded or beveled, so as to automatically effect such locking engagement upon closing the hook, and in order to again open the hook it will be necessary to press upon the knob c of the push-rod, thus causing a downward movement of the push-rod and catch E, which will allow the hook to be opened from the side of the shank, as shown in Fig. 2. The hollow shank B is struck up in opposite halves, 1) 6*, as shown in Fig. 8, and the ears I) b are made in one piece with the corresponding portions, 1) b", of the shank, so that the holdingears for the attachment of the hook-arm will be properly formed upon soldering the two parts I) b to each other, edge to edge, at the seam 22 By striking up the ears integral with their respective portions or sides of the shank, a considerable saving is effected in the cost of manufacturing chain-hooks having a pivoted hook member,

as shown and described. The hook-arm is also struck up in two opposite parts, thus forming the joint-piece d in two parts integral with the corresponding plates of the arm. It will of course be understood that I have herein set forth the preferable construction of the joint which serves to connect the shank and hook-arm; but the ears may also be separately formed and soldered to the shank.

I claim as my invention 1. The combination of the hollow shank provided with the fixed eye, the pivoted hook-arm provided with the hookstud, and the springoperated push-rod and catch arranged in the hollow of the shank, and adapted for locking the hook, substantially as described.

2. The combination of the hollow shank provided with the fixed eye, the pivoted hookarm provided with the hook-stud, the springoperated push-rod and catch arranged in the hollow of the shank, and the downward extension of the hook-arm, adapted for the convenient manipulation of the hook, substantially as described.

CHARLES F. BEYERLE.
